This law impacted any development approval issued by the former Division of Water Quality under Article 21 of Chapter 143 of the General Statutes, which was current and valid at any point between January 1, 2008, and December 31, 2010. The law extended the effective period of any permit that was set to expire during this time frame to three (3)years from its current expiration date. On August 2, 2010,the Governor signed Session Law 2010-177,which granted an extra year for a total of four(4)years extension. The Division of Energy, Mineral and Land Resources received a complete 8-year Permit Renewal Application for the subject permit on May 30, 2023. The Division is hereby notifying you that permit SW8000329 has been renewed, updated, and re-issued on June 20, 2023, as attached.

This permit shall be effective until October 13,2032, which includes all available extensions, and does not supersede any other agency permit that may be required. The project shall be subject to the conditions and limitations as specified therein. This permit does not impose new or increased stormwater control requirements; it clarifies the rules and requirements of this program to provide you with a better understanding of your obligations under this permit. Failure to comply with these requirements will result in future compliance problems. Please note that this permit is not transferable except after notice to and approval by the Division. If any parts, requirements, or limitations contained in this permit are unacceptable, you have the right to request an adjudicatory hearing by filing a written petition with the Office of Administrative Hearings (OAH).
